About Capacities
Capacities is a note-taking and knowledge management app built around objects. Instead of storing everything as generic pages, users create typed items, for example people, books, meetings or projects, and link them together so that the connections form a graph of their knowledge.
Capacities is a cloud-based application and is not self-hosted. It is relevant to people who want a more structured, database-like way to take notes than folders provide; see the official site for current features, platforms and pricing.
